13855922 divided by 907 
The aim is to understand the frequency of 907 in 13855922.

Let's proceed to step 1:
907 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 907

Let's proceed to step 2:
If we divide 13 by 907, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 907

Step 3:
907 goes into 138 0 times with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Grab the next digit (5) from the dividend, add it to 138, then carry on: 1385 / 907

Going ahead to step 4:
The number 907 fits into 1385 1 times, leaving a remainder of 478.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 907 away from 1385, we end up with 478.
Fetch the next digit (5) from the dividend, attach it to 478 and continue: 4785 / 907

On to step 5:
The number 907 fits into 4785 5 times, leaving a remainder of 250.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 4535 from 4785 to get 250.
Fetch the next digit (9) from the dividend, attach it to 250 and continue: 2509 / 907

Moving on to step 6:
907 can be fit into 2509 2 times, resulting in a remainder of 695.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
The remainder is 695 after subtracting 1814 from 2509.
Include the next digit (2) from the dividend after 695, then repeat: 6952 / 907

Moving on to step 7:
If we divide 6952 by 907, we get 7 and a remainder of 603.
The next digit of our result is 7. 
Result so far: 1527.0
Deduct 6349 from 6952 and we're left with 603.
Grab the next digit (2) from the dividend, add it to 603, then carry on: 6032 / 907

Let's proceed to step 8:
When dividing 6032 by 907, we get 6 with a remainder of 590.
Record the quotient 6 as the next digit in the result. 
Result so far: 15276.0
The remainder is 590 after subtracting 5442 from 6032.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 9:
907 can be fit into 5900 6 times, resulting in a remainder of 458.
Write down 6 as next digit of the result. 
Result so far: 15276.6
If we subtract 5442 from 5900, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 10:
4580 divided by 907 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 15276.65
If we take 4535 away from 4580, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
The number 907 fits into 450 0 times, leaving a remainder of 450.
The next digit of our result is 0. 
Result so far: 15276.65
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 12:
When dividing 4500 by 907, we get 4 with a remainder of 872.
The next digit of our result is 4. 
Result so far: 15276.6504
If we subtract 3628 from 4500, we get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Step 13:
When dividing 8720 by 907, we get 9 with a remainder of 557.
Put 9 as the next digit of the answer. 
Result so far: 15276.65049
If we subtract 8163 from 8720, we get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 14:
The number 907 fits into 5570 6 times, leaving a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 15276.650496
Subtract 5442 from 5570 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
When dividing 1280 by 907, we get 1 with a remainder of 373.
Record the quotient 1 as the next digit in the result. 
Result so far: 15276.6504961
Subtracting 907 from 1280 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 16:
The number 907 fits into 3730 4 times, leaving a remainder of 102.
The next digit of our result is 4. 
Result so far: 15276.65049614
Subtracting 3628 from 3730 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 15276.65049614, and the remainder is 1.02e-07.
